Husqvarna yard tractor?

I have a husqvarna yth2148, recently replace the motion drive belt that runs to the transmission. I had to unplug the electric clutch to it to put the belt on and now with everything together and plugged in, it wont move at all in forward or reverse. I checked and it seems the belt isn’t moving at all. Could the connector for the clutch be bad and not working right after undoing it? Another question, when I put the belt on it was incredibly tight but after I tried to drive the mower it seemed to loosen quite a bit, it’s still on the pulleys but for whatever reason it’s not as tight.

The belt that goes to the mower deck is connected to the same spot and I can engage the blades but the belt for the trans just won’t spin

It could be the connector or the belt is too loose. Is the PTO kicking on or not?
